alt Hacker NewsI've built a number of MCP servers, including an MCP wrapper. I'd generally recommend you skip it unless you know you need it. Conversely, I'd generally recommend you write up a couple skills ASAP to get a feel for them. It will take you 20 minutes to write and test some.
MCP does three things conceptually: it lets you build a bridge between an agent and <something else>, it specifies a UI+API layer between the bridge and the LLM, and it formalizes the description of that bridge in a tool-calling format.
It's that UI+API layer that's the biggest pain in the ass, in my opinion. Sometimes you need it; for instance, if you wanted an agent to access your emails, a high quality MCP server that can't destroy your life through enthusiastic tool calling makes sense.
If, however, you have, say a CLI tool or simple API that's reasonably self documenting and you're willing to have it run, and/or if you need specific behavior with a different context setting, then a skill can just be a markdown file that explains what, how, why.
Agreed. I use only one MCP server regularly and it’s a custom one integrated into my QT desktop app. It has tools for inspecting the widget tree, using selectors to click/type/etc, and take screenshots. Functionality that would otherwise be hard or impossible to reliably implement using CLI calls but gives Claude a closed feedback loop.
All public MCP server I’ve seen have been a disaster with too many tools and tokens polluting the context. It’s really most useful when you need tight integration with some other environment and can write a little custom wrapper to provide it.
